SPECIFICATION forming part of Letters Patent No. 693,099, dated February1 1, 1902.

Application filed June 14,1901.

To all whom t mag/concern;

Be it known that I, ADOLPH BAYLER, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Wrapping-Machines, ofwhich the following-is a specification.

My invention pertains to machinery for wrapping gum, chocolate, andother commodities, and has reference particularly to certain features orparts of a machine of this character set forth and described in anapplication tiled in the name of Thomas Adams, Sr., on the 31st day ofAugust, 1900, and designated by Serial No. 28,678. The improvementsrelate particularly to the mechanism for actuating the nippers orgripping devices by which the paper strip from which the wrappers arecut is drawn forward.

In the particular work for which the machine above noted was primarilydesigned an inner wrapper of parafined paper and an outer wrapperbearing certain printed matter or devices are employed. The printedmatter is repeated a number of times on each strip from which the outerwrappers are cut, and in order that each wrapper may bear its fulllegend or device and not cut into or carry a portion of that belongingto the next wrapper it s essential that the strip be advanced a definitedistance each time. Owing to atmospheric changes and to thehygroscopicnature of paper it is found in practice that in some weather the stripelongates and in other weather contracts. As a consequence thewrapper-blanks cut therefrom are not always severed 0n the properlinesbetween successive designs or printed forms. In some other caseswhere the strip is elongated it happens that after several blanks havebeen cut the printed matter or design thereof will be partially clippedor cuto, while when the strip contracts there will sometimes be oneentire design or form and a small portion of another on the same blank.To obviate this difficulty, I provide means for varying the throw of thelever by which the grippers are operated, so that while going always toa given point to grasp the forward end of the wrapper-blank they shallbe caused to move therefrom a greater or less distance, according to theat- Serial No. 64,622. (No model.)

mospheric conditions and the consequent condition of thewrappermaterial.

Another serious difculty encountered in the practical operation ofmachines of this general class resides in the liability of the bladesormembers of vthe cutting devices to play slightly or get out'ofalinement, and consequently 'to produce a ragged or tearing cut. Toobviate this difficulty, Iguide the two members and the actuating-leverof the cutting device in ways, and I provide a yielding pressure-plateto press and hold one blade in close contact with the other. Theconstruction of parts whereby I attain these ends is represented in theaccompanying drawings, in Which- Figures 1 and 2 are sectionalelevations showing the grippers and their actuating mechanism and alsothe adjusting devices to which the present invention pertains; Fig. 3, asectional View of the actuating-lever and its supporting and'adjustingdevices; Fig. 4, a view of the actuating-lever and its adjusting deviceslooking from the opposite face from that seen in Figs. l and 2; andFigs. 5 and 6, elevations of the cutting devices and their actuatingmechanism, the bed or table upon which the cutter is mounted being shownin section. Y

Referring first to Figs. l, 2, 3, and 4, A represents the bed or tableof the machine; B, a trough in and through which the strip of paper orother material from which the wrapper is formed is fed. Thisjstrip isfirst advanced along the trough until its forward end encounters acutting knife or blade C, which rises from beneath and passes through anopening in the bed or table B, coacting just above said bed or tablewith .a blade D and plate E, the latter urged and held toward the bladeD by spring a, encircling a screw-stem b, which passes through a hole oropening in the blade D and screws into the plate E, the spring ct beinginterposed between Vthe head of the screw b and the blade D. These partswill be more fully describedlater on. When the parts C and D separate,nippers F, comprising a fixed blade c and a pivoted blade d, advancetoward the delivery end of the trough B and grasp the protruding end ofthe paper or wrapper strip. As the construction and IOO operation of thenippers themselves constitute no part of my invention, but are set forthat length in the application of Thomas Adams, Sr., above mentioned, itis unnecessary to make further description of the same herein. isconnected by a link II with a lug on the under side of the gripper orthe slide which carries the gripper. This lever G is atits lower endcarried by a pivot-bolt I, which passes eccentrically through a circularboss or hub e of a rocking block or yoke J. The circular hub or boss eof the yoke J is accurately fitted in a block or standard K, whichconstitutes a bearing for said boss and which also has a foot or baseplate to give steadiness and bearing for the standard upon the base orbed of the machine. The foot or base plate of the standard K isslotted,as shown atf, Figs. 3 and 4, to receive the lower end of thelever G and preclude displacement thereof. As shown in Figs. 1, 2, and4, the yoke J is formed with two upwardly-extending ears, which projectfrom one face of the yoke into line or plane with the upright portion ofstandard K. These lugs or ears are tapped to receive thumbscrews L,which, bearing against opposite edges of the standard and being turnedone forward and the other backward, serve to adjust the yoke or to swingit about the axis of the circular boss or hub e. The yoke J is slotted,as shown at g, to receive a bindingscrew or tap-bolt M, which, passingthrough said slot and entering a hole tapped in the standard, serves tobind the yoke to said standard and to hold it in its adjusted position.As the bolt I, which constitutes the pivot of lever G, is eccentricallylocated in the hub or boss e, it follows that as the yoke J is rockedthe position ofthe said pivot-bolt I willfbe varied. With the yoke inits medial position-that is, with its ears equidistant from the standardK-the pivot-bolt I will under the preferred arrangement of parts occupya position vertically beneath the center of the -boss e. Hence uponrocking the yoke J to one or the other side the axis of the bolt I, andconsequently the pivotal axis of the lever G,will be thrown slightly toone or the other side of a vertical line passing through the center ofthe hub or boss e. This will of course vary the distance to which thelever G Will be thrown in one or the other direction.

In approaching the strip the nippers, which are at the moment open, maymove a slightly greater or less distance without affecting the finalresult, as they will simply seize the paper a little nearer to orfarther from the end of the trough or guide B; but the outward orbackward movement of the nippers must be in exact proportion to thelength of blank or wrapper required. By shifting the pivot or fulcrum ofthe lever G in the manner above described this result is accurately andcertainly attained. The thumb-screws L afford means for accuratelyeifectin g the adjustment G indicates an upright lever, which and fortemporarily holding the parts until firmly clamped by the screw or boltM.

In practical operation this device is found to meet and answer perfectlythe conditions above stated and to enable the operator readily to adjusthis machine according to all variations of atmospheric conditions.

Figs. l and 2 show the yoke and the pivot for the lever in the medialadjustment. Fig. 4 shows it shifted to one side of the center of the hubor boss e, as shown by the relation of the pivot-pin to the dotted linepassing vertically through the axis of said boss or hub.

Referring now to Figs. 5 and 6, illustrating the cutting mechanism ofthe machine, which, as before indicated, coperates with the gripperdevices, the improvements thereinwill he explained. Secured to or formedupon the under side of bed or table A are vertically grooved or slottedguides h, in which moves a slide N, which carries the lower blade orcutting member C and which is reciprocated vertically by an elbow-leverO, fulcrumed in or upon a lug depending from bed or table A andfurnished with a stud or bowl, which extends into a cam-groove j in arotary cam wheel or disk P. On the upper side of the table A arestandards k, having horizontally- Aprojecting ears or brackets l, bothof said standards being slotted or bifurcated at their upper ends, oneto receive the pivotal en d of a lever Q and the other to guide the freeor moving end thereof. A pin m, passing through the upper end of one ofthe standards l; and through lever Q, forms a fulcrum or pivot therefor.The guiding of the free or moving end of the lever Q in the slotted postor standard la is important for the reason that it is thereby given astraight-line movement and is precluded from exerting any lateral ortipping strainupon the upper cutting blade or member D, to which itgives motion. The upper blade or member D is extended lengthwise beyondthe limits of the lower blade C, and the extensions are vertically boredor perforated to t closely about vertical guiderods fn., the lower endsof which are seated in the bed or table A of the machine, while theupper ends are held in the projecting lugs or brackets Z of thestandards It. This makes a firm and rigid construction and in- IIO suresthe true vertical movement of the blade strip which the cutter isdesigned to sever.

To completelyl guard against this, there is applied to the rear face ofthe cutter D a pressure-plate E, which is preferably connected by ahinge o, as shown in Figs. l and 2. This pressure-plate is normallydrawn to ward the cutter D by a spring a, encircling a screw-threadedstem b, which passe sthrough an opening in the cutter D and is screwedinto the plate E, as shown in said iigures. The Spring d, encircling thestem l) and lying between the front face of cutter D and the head of thestern ZJ, tends constantly to draw the plate E into close contact withthe blade D, and the degree of pressure may be varied, as desired,byadvancing or backing the screwstem b. The inner face of the plateE isbeveled slightly from the lower edge upward, as seen in Figs. l and 2,to insure proper entrance of the thin cutting edge of the lower blade C.The construction thus described insures close contact of the proximatefaces of the upper and lower cutters D and Gand the consequent cleanseverance of the strip, the plate E yielding to permit the cutter C torise to its proper height relatively to cutter D and between itandtheplateE. TheplateEservesthefurther purpose of a presser-foot toprevent the wrapper-strip from being carried upward past the lower edgeof the cutter D. Connection is made between the lever Q and the cutter Dby means of a short link T, suitably pin- `jointed to the respectivemembers, as indicated,this connection affording sufficient play betweenthe lever and the cutter to prevent cramping or binding of the latter,while leaving it free to follow a true vertical path. The lever Q israised and lowered through the medium of a lever U, fulcrumed in a postor standard Vin the baseor bed of the machine and having one endconnected by a rod or link WV to the lever Q, its other end beingprovided with a stud or bowl r, which, projecting into a cam-groove s inthe wheel or disk P, is given the requisite vibration. The grooves j ands of the cam wheel or disk P are of course fashioned with due referenceto each other and to the movements to be given to the respective bladesor members and are such as will insure a simultaneous descent of theupper blade or member and rise of the lower blade or cutter. Preferablythe lower blade will be caused to withdraw before the upper member risesfrom its cutting position, but this is not essential.

Vibratory motion is imparted to lever G, which actuates the nippers, bymeans of a cam wheel X, the periphery of which is grooved to receive astud or bowl t, projecting from the lever, as indicated in Figs. l and2.

Features illustrated in the drawings but not herein described are not ofmy invention, and hence need not be further referred to, nor have Ideemed it necessary to show the entire machine, since the featureshereshown and described may be sufficiently explained and fully understoodwithout encumbering the description with matters not original withmyself.

The embodiment of the invention herein set forth is deemedtiierbest ofseveral forms in which it may be made; but it is to be understood thatthe adjustable pivot I may be modied as to its mode of adjustmentwithout departing from the general lines of my invention. So, too, thecutter may have its guides varied in form, and the plate E may beotherwise attached to the upper blade B, provided only it be heldthereto by springpressure and be left free to move therefrom to theextent necessary to admit the blade C.
